Method for operating a through-feed press in the course of the production of chipboard, fiberboard, laminate boards and the like, as well as for the process established feed-through press

摘要

The panel press with heated pressure plates (5,7), carried by upper and lower frames (4,6) between which the material passes, also has steel bands (9) between the material and plates. Associated with the bands are pick-ups (13) passing signals to a control circuit (16), which adjusts a network of rams (12) for pressure regulation. The control circuit includes an actual rated value equaliser (17), a controller (18), and regulators (19) which adjust the pressure according to the difference between the actual and rated values. USE/ADVANTAGE - For chipboard, fibre boards, laminates etc. Close control of the travel of the steel bands.
